While dying in 1112, Tancred made Pons of Tripoli, promise to marry her, and Tancred gave her the fortresses of Arcicanum and Rugia as a dowry. They married in 1112. In 1133, Pons was besieged at his castle of Montferrand by Imad ad-Din Zengi, atabeg of Mosul, in 1133, and Cecile appealed to her half-brother Fulk, King of Jerusalem, to come to his aid. Zengi abandoned the siege, but during a second siege in 1137, Pons was captured and killed. He was succeeded by his son with Cecile, Raymond II. Cecile died in 1145.
